To aZZ 'whom z't may concen'n: .v

Be it known that we, WILLIAM RHoDES KENNETH VOLLAMS, citizens of theUnited States, reslding at Worthington, in the countyof Greene and Stateof Indiana, have invented certain new and useful Improvements inlVrenches, ofwhlch the following is a specification, reference being hadto the accompanying dra-wings.

This invention relates to .wren'chesjland more particul'arly to .a quickadjustable wrench.

It is an object of the invent'ion to Vprovide a wrench of this Characterwherein the Ino-v.-

able jaw can be adjusted to the size desired' without the necessity ofrotating any adjnsting-means ,on tightening the jaw after. `it isadjusted.

,It is a further object ofthe invention to provide a. wrench of :thisCharacter whereinl the body member ofthe wren-ch substanti'allyservesasa wedgein the tightening operation.

It is a still further'objectof the'invention to provide a device ofthischaracter-wherein the i adjnstingmeans within the movable jaw and themovable jaw are' both adapted for bindingl.y engagement [with the bodymember ofthewrench. i

With' these and other objects 1n view, the

invention consists in the improved' con-V struction and arrangement ofparts to be hereinafter more practically described, fully claimed andillustrated in the accompanying drawlngs7 in which Flgure 1 is a s1deelevatlon of a wrench i constructed in accordance with van embodiment oftheV invention, and showing the parts in the position they occupy whenthe wrench is being adjnsted;

In connection with the body memberV and the stationa-ry jaw 8, a movablejaw member 9 is used, said jaW member comprising ,movable an elo'ngated;block; theend 10 of. said block serving as the jaw. The longitudinaledge 11 of the block 'is provided with a plurality of`teeth'12, adaptedto engage.the front face 6-of .the body member. The oppositelongitudinal edge 13 of the blockisprovided with spaced recesses 111andl. Thev lower end 16 of the block 'is curvedinwardly j toward 'theedge 11 to lfaciltate adjustment of the'wrench. i. `ln connectionwiththep'movable ja.w, a slidingV member 17 isprOVided, said. levercorresponding in width to the widthof the rear face 7 of the bodymember.l The memf. ber -17 is intended for sliding movement on theA rearface of the body. member andv longitiidinally of said face.VV One endportion of the member is provided-with spaced recesses 18. andl 19, saidrecesses .eXtending throughV the sides of the. member.V

'.n orderv to connect the lever to the mova-` ble'jaw,A connecting rings20 andl are pro-,i

i vided, each of said rings. being substantially oblong in shapel andslightly greater in` length thanthe 'distanoe between the recesses ofthe movable j aw member 9 and thezmemher 17. The 'ring 20.is adapted .tobe disposed in the reoesses 14; of the movableljawVvr member 9 and therecess 18 of thejlever 19` while the ring 21 is adapted to bedisposed inthe recess 15 of the mova'ble jaw member the j aw mem er 9 adjacent therecess 14 and ring 20 whereby to hold the adfjacent ring 9 and therecess 19 of the member 17. AV

stop member 22 is carried by one sideface of,V

Vit is'adapted to be engaged byt-he adjacentM i 20 and the ring 21 atright angles 'to the member 17 the jaw 9 and bodylmember or shank 5,'Vso that the member ,17 and bin ding.

jaw 9 may be: adjusted without To adjust the wre-nchthe member 17 is o 1moved longitndinally of the bodyl member permit the ring 20 tol engagethe. stop-2% This positions the ring in'a per-o so as to penducularposition and permits the '-movable jaw member 9 to be movedrlongitudivnally` of the body member 5, together with o the member 17. When the'jawmember V9 .has reachedV the. desired point, or in 'others words, whenthe jaw member-9 comes 111 K contactfwith the vob'jectto be tightened,the' movement `of the member 17 is continued by hand so as tosubstantially dispose the ring 20 and 21 in an oblique position withrespect to the side faces'of the body member 5. of the movable jaw andthe sliding member itis only necessary to move the member longitudinallyof the body member and away from the stationary jaw 8 so as to 'permitthe leverl 20 to engage the stop member 22. This positions both ringssubstantially in a perpendicular position with respect to the axis ofthe body member 5, thereby permitting both the member 17 and the movablejaw to -be moved longitudinally of the body member' unobstructedly tothe desired point.

From the foregoing it will be readily seen that this invention providesa novel form of wrench which can be quickly adjusted and'maintainedindefinitely in its adjusted position in'vlew of the binding engagementof the lever and movable, jaw on the body member. In view of the factthat the mova'ble jaw does not depend for its support on teeth orscrews, it may be used for very heavy work without danger of 'the setposition of the jaw being disarranged. Furthermore, it may be adjustedto the eX- act size of't'he member to be tightened. It is of courseobvious that we do not desire toV limit ourselves to the particular formof jaws shown as both the work engaging faces of the stationary jaw 8and the movable jaw member 9 may be provided with teeth to permit thewrench to be used in connect-ion with pipes or tubular objects.Allofthese features are possessed by a structure which is simple andsubstantial and which can be manufactured from a small amount ofmaterlal.

VVhat is claimed 1s:-

To break the 'binding engagement 1. A wrench coinprising an elong'atedshank terminating at one end in ai'elatively fixed jaw, a block'slidablymounted upon serving as a relatively movable jaw'rcooperating With saidfixed jaw, an elongated actuating member slidably disposed against theopposite edge of the shank, the outer edges of the member and blockbeing formed with. recesses, elongated loop-like elements engagedwithinsaid recesses' and embracng` the block, shank and member, and stopmeans on the 'block eng'ageablel by one loopl .one edge of the shank andhaving one end site edge of the shank, the outer edges Vof the memberand block being formed withV recesses, elongatedV loo'pelik'e elementsengaged within said vreces'ses and embracing the block, shanl: andmember, and a pin4 rigidly fixed to and projecting from the block andengageable by one loop element to serve as a stop for maintaining bothloop elements in a position perpendicular' to the shank whereby themember and block may be slid freely along the shankf In testimonywhereof we hereunto affix our signatures. 7
